The FC1500-ULNnova is Menlo System’s latest optical frequency comb synthesizer for
ultimate performance. The core of the new model consists of a redesigned comb oscillator, based on the patented ultra-low-noise (ULN) figure 9® mode locking technology.
The enhanced design of this so-called “nova”-oscillator results in significantly improved
robustness against acoustical distortion and thermal drift. The major benefit is a reduced
free running linewidth of only 15 kHz. Owing to this leap in linewidth reduction, theFC1500-ULNnova has proven to support a frequency stability on the 10-19 level* for 1 s
averaging time!
Ever increasing demands for stability and accuracy of time and frequency signals require
improved frequency references. But even the best optical references have very limited
spectral coverage. The FC1500-ULNnova overcomes these limitations by transferring thespectral purity of a stable reference to the entire wavelength range of 500-2000 nm. This
unique feature enables the users to compare different (optical) frequency references,stabilize all CW lasers to one absolute frequency reference and use it as a clockwork for
optical clocks. The overall frequency stability is evaluated in an out of loop comparison
between two independent optical frequency combs, which is integral part of the quality
check during factory acceptance of each system.
*Fractional ModADEV. Specifications regarding frequency stability will be updated soon.
